PERFORMANCE OF LLC RESONANT CONVERTER FOR ELECTROLYSER APPLICATION

摘要

Electrolytic hydrogen offers a promising alternative for long-term energy storage of renewable energies (RE).The long-term excess energy with respect to load demand has been sent to the Electrolyser for hydrogen production and then the fuel cell has utilized this stored hydrogen to produce electricity when there were insufficient wind and solar energies with respect to load requirements.The RE system components have substantially different voltagecurrent characteristics and they are integrated on the DC bus through a power conditioning devices for optimal operation.The DC power required by the Electrolyser system is supplied by the DC-DC LLC resonant converter.The simulation and experimental results show that the power gain obtained by this method clearly increases the hydrogen production and storage rate from wind-PV systems.
